The p[roblem is at exposure. First lubricate rails tec. Is scaner mooving smoothly?
What about sensor?

Could be a short circuit within the system. On a different machine, (MPC4501) i had these SC 1XX a couple of years back. I swapped most of the boards that are related to it in our workshop but couldn't fix. When I checked the service history, the last call was to replace the Transfer Assembly. Tech did not tighten the screw properly and was grounding the system. Had to tighten the screw and just like that, problem solved.

My 2 cents
